IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 169,390, dated November 2, 1875; application led l September 11, 1874.

To all whom it may concern Be it known that I, CHARLES WARREN, Captain Royal Engineers, of Shoeburyness, in the county of Essex, England, a subject of the Queen of Great Britain, have invented or discovered a new and useful Improvement in Stoves 5 and- I, the said CHARLES WARREN, do hereby declare the nature of the said invention, and in what mannerthe same is to be performed, to be particularly described and ascertained in and by the following statement thereofLthat is to say:

The object of this invention .is to construct a stove in such a manner that more perfect combustion of the fuel consumed therein may be obtained than in ordinary fire-places or stoves. For this purpose, in place of the inletto the due or chimney being above thel fuel. as is for the most part customary, I form it at the back of the fire-place, just above the firebars or surface on which the fuel rests, and in line with or opposite the front re-bars. The supply of coal for keeping up the fire is thrown on at the top, in the ordinary manner, and is covered over by a closelitting plate, which may be used as a hot plate. The greater part of the air for supporting combustion is admitted between the front lirebars, and, passing horizontally among the burning fuel, is consumed, and escapes at the outlet-due at theback of the fuel-holder, partly in the state of carbonio oxide. Near this point a fresh supply of air is, by a suitable passage, admitted to it to complete its combustion as it passes away. Thus the production of smoke is entirely avoided. As the fuel at the lower part of the lire is thus being consumed the coals above descend and take its place, and, as they descend, become gradually coked, the gases given ol being, by means of the chiinneydrait, drawn downward among the ignited fuel and there consumed.

Figure l represents a perspective view of a large-sized cooking-stove. Fig. 2 represents a vertical section of the same, and Fig. 3 represents another vertical section at right angles to Fig. 2. In these figures, A is the stove casing or body, and a is a box head or hopper of a magazine or holder for containing the fuel. This box or hopper is cast or framed with front and back gratings b b near the bottom. The air for supporting combustion passes in through the front grating, and the products of combustion pass out through the back grating. In the top of the hopper is an opening, through which the fuel is introduced, provided with a closely-fitting lid, c. d el are fire-bricks, which form the sides of the firebox, and e is a grating upon which the fuel rests. f is an ash-pit. g g are dedectingplates for the purpose of retarding the escape, and thus aiding in securing the complete conlbustion, of the gases. h is a boiler, and la is an oven. The products of combustion which escape through the back grating are partly composed of carbonio oxide, and to effect the combustion of this substance a further supply ot' air is admitted in rear of this grating through the pipe i. The products of combustion are then, as shown by the arrows,

conducted to and fro in a zigzag course by the dedecting-plates g g, which overlap one another in the center of the saddle-shaped boiler, and finally either around the oven It, or directly, as is usual in stoves, off through the flue or chimney m.

By this organization. a continuous feed and a complete combustion of the fuel are accomplished.

I am aware that a continuous feed, such as I have adopted, is not new, and that a horizontal draft through the fuel in a tire-box is not new, and that detlecting-plates are not new, and that to supply air to the products of combustion in rear of a fire-box is not new, and I not claim to have invented any one of these things; but what I have invented is the particular organization of all of these elements which I have described and shown; and

What I claim, and desire to secure by Letters Patent, is

The combination, in a stove, of a box or hopper, east or framed with front and back gratings near its bottom, through which a continuous feed and a horizontal draft are obtained, and air-supply pipe in rear of said box or hopper, and deflecting-plates arranged behind the box or hopper, on opposite sides of the flue, one overlapping another, so as to drive the products of combustion from side to side in a zigzag course, thus greatly retarding them, substantially as described, for the purpose specilied.
